The provisional data presented in this visualization include: (a) the reported and predicted provisional counts of deaths due to drug overdose occurring nationally and in each jurisdiction (b) a U.S.
To address this, methods were developed to adjust provisional counts for reporting delays by generating a set of predicted provisional counts (see Technical notes). Provisional counts are often incomplete and causes of death may be pending investigation (see Technical notes) resulting in an underestimate relative to final counts. National provisional counts include deaths occurring within the 50 states and the District of Columbia as of the date specified and may not include all deaths that occurred during a given time period. Counts for the most recent final annual data are provided for comparison. This data visualization presents provisional counts for drug overdose deaths based on a current flow of mortality data in the National Vital Statistics System.
Please see the Technical Notes of the dashboard for more information on adjustments for delayed reporting. Recent trends may underestimate the death count in affected states and this potential impact should be considered when comparing results for states to previous months. In recent months, certain states have experienced longer than usual delays in submitting drug overdose deaths. UPDATE : The Monthly Provisional Drug Overdose Death Counts report provides estimates for the United States and jurisdictions within 4 months after the date of death.
